Four months after Philip Seymour Hoffman's death from a drug overdose, his neighbours have filed a $90k lawsuit on his estate.

Gene Hoffnagel and Anna Erdelyi lived below the actor's $1.4 penthouse in the West Village, New York, when their apartment flooded in 2011.

The cause was a faulty pipe connection between a hot-water supply and kitchen tap in the actor's apartment, which he used as an office and guest home, the couple’s lawyer Mark Seitelman said.

It meant the couple were forced to leave their place for 11 months while structural damage was repaired, according to the lawsuit.

The Manhattan Supreme Court suit, which also named the actor's on/off girlfriend Mimi O'Donnell, is looking for $87,329 which “represents their out-of-pocket loss to fix the apartment to what it was before,” said Seitelman.

“They have no ill will toward H​​offman."

The Capote actor was 46 when he died in February and owned the flat with his long-term girlfriend Mimi, the mother of his three children, Cooper, ten, Tallulah, seven and Willa, five.

Despite being estranged from Mimi at the time of his death - and living in a bachelor pad nearby, where he was found dead - he left the bulk of his money to her.

The talented actor, whose estate is believed to be worth $35 million, won an Oscar in 2005 for his performance as writer Truman Capote and was nominated for the Best Supporting Actor gong on three occasions.
